a {em roman dominating function} on a graph $g$ is a function$f:v(g)rightarrow {0,1,2}$ satisfying the condition that everyvertex $u$ for which $f(u) = 0$ is adjacent to at least one vertex$v$ for which $f(v) =2$. {color{blue}a {em restrained roman dominating}function} $f$ is a {color{blue} roman dominating function if the vertices with label 0 inducea subgraph with no isolated vertex.} the wei...

In this paper we study the numerical integration on (−1, 1) with respect to the Jacobi weight function (1−x)(1+x), where α and β are complex parameters. The problem arises in some applications of computational models in quantum mechanics. We discuss two methods for integration. One is suitable for integration of analytic functions and the other is applicable to the general Riemann integrable fu...

Abstract This paper proposes a new method to improve performance of AdaBoost by using a distance weight function to increase the accuracy of its machine learning processes. The proposed distance weight algorithm improves classification in areas where the original binary classifier is weak. This paper derives the new algorithm’s optimal solution, and it demonstrates how classifier accuracy can b...

The aim of this paper is to propose a joint cross-layer approach between application layer and MAC layer for enhancing Quality of Service (QoS) for multimedia applications. Bandwidth adaptation scheme based on application utility function is used in the application layer as it reflects the satisfaction degree of end-users with the allocated bandwidth. Prioritized Weight Assignment (PWA) in MAC ...

background: thyroid function disorders, particularly congenital hypothyroidism (cht), are important endocrine dysfunctions associated with permanent morbidities. cht is more prevalent among preterm low-birth-weight neonates compared to term infants with normal weight. methods: this prospective cohort study was conducted on 126 very-low-birth-weight (vlbw) neonates referred to the neonatal inten...

Since the maximum possible score becomes 7, we defined severe pneumonia as a score >4 for the CURB-age criteria compared with >3 for CURB-65. The subjects were 189 patients (median age 75 years, range 17–96, 56.1% men) who were included in two prospective observational studies of CAP. Detailed methodology has been reported previously. 5 Using CURB-65 there were 109 non-severe cases (57.7%) and ...
